Application filed November 19, 1927. Serial No. 234,386.

lhi'sim entiOn relates to furnaces for use of gaseous or vaporized fuels. V v I The general purpose of the invention is to; provide an improved radiatorv construe tion for suchfurnaces whereby'more efficient heating will result.

Particularly the invention has for its ob: jectthe provision of a radiator including one or more radiator units to which the combusted gases are supplied from the central fire pot by ducts extending upwardly and outwardly and-from which thegases are delivered by duets upwardly and" inwardly toward the center of the furnace whereby the heat in the gases. will be more completely ducts which: distributethe combusted gilfiiQS.

to, or deliver the'gasesfrom, the radiator.

The forego ng-and other ob ects are at tained in the construction illustrated in the accompanyingdrawings and described be low. It is to be understood that the inven tion is not limited to the particular con; struction shown and described.

, Of the accompanying drawings,

Figure'l is a perspective view of a furnace embodying the invention, partly broken awayto illustrate the interior construction;

, Figure 2 is a. vertical diametral section through the fire pot and radiator thereof; Figure 3 is a sectional plan on line 3.3 of Figure 2;

Figure 4 is a detail, vertical section illus trating the joint between the radiator ducts and the radiator dru1ns;-a.nd 1

Figure .5 is an inner elevation of a drum at a port to which a radiator duct is fitted as shown in Figure 4f.. 2

Referring to the drawings,the numeral indicates the usual furnace casing, provided with connections indicated at 10 for the usual air ducts andhavingtherein a firepot 11 containing a burner 12 of that type employed for; combustion of. natural or artificial gas. which may be supplied to the burner by piping 13. V

The fire pot 11 is provided with a dome piece 14: from which radiate outwardly and upwardly, ducts 15, 15 on wliich is seated anflannular. hollow radiator drum 16. Drum 16 has ports :17, 17 registering. with ducts 15 for conductingthe gases of. combustion from the the pot into the drum 16. Tubes 18, 18

extend upwardly through drum 16 and permit passage ofair thercthrough, to increase the radiating surfaces of the. drum, alternate tubes preferably being radially offset, and certain of tubes 18,-.as. illustrated in Figure 3, being opposite ports '17 so as to divide up thestr'eamsof gasesof; combustionenteringrthe drum and thoroughly to distribute them to all of its radiating-walls.

The drum 16 has outlet ports1l9, 19.011 the inner periphery thereof adjacent the top,

flanged, asindicated at20 and20 Figures 4L and 5, to supporta duct spider comprising a. single casting includingradial ducts 21, leadingto a central duct 22. Ina, single unit. construction the duct 22 may-be connected directly with a flue. I

In the double unit construction herein shown'duct 22 is flanged at its upperedge 23 to receive and support. thereona second duet spider casting comprising a central duct 24 fitted onto the top of; duct 22and radiating ducts .25, 25 for conducting the gases of. combustion tov second: radiator drum 16, thespider casting includingduct 2 1 and ducts 25 providing a support for drum 16 upon the radiator. structure previously described.

Drum 15 has ports 17? registering with ducts'25 andhasftubes 18518 similar to tubeslS and has outlet ports 19 similar to ports 19 for delivering the gases of co'mbustion from theradiatortintof athird duct spider including radial ducts 2 6, 26 and central duct 27. which emptiesinto a flue 28.

The spider including duct 27 and radial ducts. 2 6 is supported by fiangessuch as 20 and 20 about the ports 19f. The drum 16 and duct, spiders, employed: therewith pro vldei'adiating surfaces similar to drum 16 and itsassociat ed duct spiders. course,

From central duct 24-, the gases pass throughducts 25 and into and through drum 16* in a manner similar to their passage through drum 16. From drum 16 the gases pass through ducts 26 and duct 27 to flue 2?, the heat thereof having been very elficiently utilized in warming the air in the'furnace about the radiator. The paths followed by the gases of combustion are indicated in the drawings by full-line arrows.

The air about the radiator finds paths permitting free upward flow thereof about the fire pot and drums 16 and 16 through the tubes 18 and 18 and through the central openings of the drums in paths along the inner peripheral walls thereof and about the radial ducts through which the combusted gases are conducted to and from the drums.
